Abstract:
An antenna system may include a first phase shifting network to output a first set of component signals from a first component signal having a first frequency, a second phase shifting network to output a second set of component signals from a second component signal having a second frequency, the first frequency being less than the second, and an antenna array, the first phase shifting network to impart a first tilt angle for the first set of component signals, the second phase shifting network to impart a second tilt angle for the second set of component signals, and a single variable electrical tilt controller to control the first and second phase shifting networks and being configured to maintain a ratio between the first tilt angle and the second tilt angle, where the first tilt angle is greater than the second tilt angle, and where the ratio is less than one.
